Are you suggesting that schoolboys choose their textbooks? I don't doubt these boys were being propagandized by the PA. That only makes them doubly victims, and in no way mitigates the criminal indifference to human life of those IDF elements who placed a deadly hazard in their way.
Upon hearing of the IDF bomb that killed those kids, there was an uproar in the government and within Israeli society.
An investigation was launched. Newspapers critisized. Here is the big part: Not a single Israeli cheered, danced in the street, handed out candy, celebrated... The government mourned the loss, gave its condolences, and not a single official praised their deaths. Not a single religious leader praised their deaths.
Not take everything i've just said, and take the complete opposite on every SINGLE sentence. Now you've got the Palestinian (civilian, government, religious) reaction to the deaths of dozens of Israeli children.
Why is this?
Btw, not that I don't think this is a tragedy, but just so you know, these Palestinian 'clans' ("families) sometimes number many thousands of people. When the Palestinians killed 5 members of the same Israeli family in the Pizza Parlor (family of 8 i believe) they praised the murder.
